I used that inspiration to create my own portable 3D printer workbench:

The base is the IKEA BEKVÄM serving cart nearly unmodified. I just did not install the middle wooden grate. Instead I took it apart and used the wood peaces to create the slides for the plastic trays. The plastic trays are IKEA ANTONIUS 25l trays with lids, but I think they are not available anymore.

On the front and the two sides, I fixed 40 cm long IKEA GRUNDTAL rails. One is used as a handle when moving the cart and they can all be used for hanging all kinds of stuff. I have a variety of accessories - also mainly from the GRUNDTAL series in use.

The mounts for the rail in the front had to be shortened a bit and a new hole drilled to keep them out of the way of the trays.

On the backside, I mounted a power extension lead with six sockets. On the left side, I fixed the power supply of my UM2 with the power supply holder created by Labern.

I then drilled a hole trough the top and mounted a lazy susan ball bearing on top with a square piece of wood as turntable. The turntable has the same hole in the middle. This allows me to feed the cable from the power supply to the printer through the middle of the desktop and under the printer to the power socket on the back of the printer. This way the printer can rotate >360° without any issues.

The printer sits on some noise dampening feet printed from FlexPLA that also prevent it from moving on the turntable.

Great hack, I've had my UM2 on a lazy Susan too for over a year now, great for getting easy access all round the printer.
I was considering the serving cart but now I must take another look you've done a great job.

The only thing it's missing, is being enclosed somehow. I'm looking for a good solution to put multiple 3D printers and a CNC router / grinder / lathe all in one workshop. But that means I have to separate all the machines from each other because some generate dust and others shouldn't be exposed to dust.

I was thinking of using IKEA IVAR shelves and adding acrylic walls & doors to it. But these shelves only have a 25kg load rating. The printer I'm building will be heavier than that... I suppose adding a little more weight won't be a problem though.

As you can see, it's a really tiny space, so I made this custom table / bench for my printer from regular, laminated chipboard (16 mm and 18.5 mm) I had from a previous project. All was sketched in 123D Design (to fit the filament boxes, printer, spool holder, the two insulated pipes runing down the wall etc.) and then cut in my garage using a jigsaw (from hand, pain in the ass to make straight cuts...). Also the drawer was then hand cut and all glued and screwed together.

Pictures of the current state, completed:

My version of the spool holder from IRobertI, re-designed completly in F360 to also fit DiamondAge Spools . Mounted on a 25mm aluminium pipe cut to lenght (the height of the spool can be adjusted of course):

Some more detail of my mechanism to mount the pipe (the red piece is ninjaflex, the thread clamps the pipe with the ninjaflex piece) here you can also see the cutout for the piping:

The drawer in detail, the handle is of course 3d printed, designed in F360:

And then some storage of course:

The printers feet (https://www.youmagine.com/designs/ulti-foot + Longer Version (Heated Bed Power Supply) + instead of rubber bands, ninjaflex inserts). You can here also see how I connect my HBK PSU (had to cut my UMO, that really did hurt!) inserted proper connector with light and fuse, so I can shut down the heated bed seperatly from the UM itself:
